Do the Diamond pistons come in 3.904 or what overbore sizes?

3.905 is the most common overbore size. That would be a shelf piston too so they are cheaper then customs, unless you need some custom for high FI use.

Do they have an off the shelf 9:1, 3.905 bore piston? I'd really prefer 8.5:1 but let me know.

There is a shelf 3.905 with a -8.6cc dish available. You'll just have to plug in your stroke, gaskets, and CCs and get the compression, or let me know the numbers and I'll do the math. Other then that it's going to be a custom.

We can also turn down the shelf stock pistons we have to std. bore. Our cost to do that is $30.00.

Remember also, that #11503 is our turbo/blower piston. It was designed to handle up to 20lbs of boost. With 70cc heads it should give you around 9:1 comp ratio.
